The sidecar that isolates all MCP wire complexity from the soul. Binds
loopback 127.0.0.1:7771 only. The soul reaches it over flat HTTP; the bridge
owns stdio/streamable-HTTP transports, OAuth (PKCE), Keychain secrets, server
lifecycle, config, and a tool-schema-hash poisoning guard.
HTTP contract: GET /mcp/tools, /mcp/servers, /mcp/auto-approved, /healthz;
POST /mcp/call, /mcp/oauth/start, /mcp/servers/{add,toggle,auto-approve,
remove,secret}; GET /mcp/oauth/callback.
Config: ~/.neuron/connectors.json (servers, no secrets). Secrets in macOS
Keychain (service ai.neuron.connect, account = serverId). Spec:
docs/research/mcp-connectors-adoption-spec.md.
Phases 1-3 verified end to end (stdio + HTTP transport, Keychain token auth,
OAuth round-trip); Phase 4/5 (CRUD + auto-approve + schema-hash) added for the
ConnectorsView UI.
